specification.

This invention relates to the drawing mechanisms of spinning frames and the like,

and it is especially concerned with the mechanism for weighting the drawing rolls to enable them to properlyperform their drawing function.

Heretofore it has been customary to weight one or more of the top rolls of each set by'means of springs or various combinations of weights and levers, and to clear the rolls of the lint and similar forei material that collects on them by runmng them in contact with a revolving clearing cloth or with a stationary covered board.

With a view to simplifying this mechanism, it has been proposed heretofore to Weight and clear the front top rollby means of a heavy cloth covered rollru'nning directly in contact with it and resting on it. While this arrangement is an improvement on the construction previously used, 'it is nevertheless open to the ob'ection that the combined clearing and weig ting roll must itself be cleaned at intervals, andthis roll is necessarily so heavy that the cleaning operation is thereby made difficult and awkward. It is the chief object of the present invention, therefore, to devise a construcamsm. v

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawin and the novel features will be particu arly pointed out in the In thedrawings,

Figure 1 is a'plan view of a portion of a spinning frame embodying the present invention;

The drawings show the invention applied to a spinning frame of well known construction. This mechanism comprises a stand or frame 2, a front pair of upper and lower drawing rolls 3 and 4, respectively, intermediate. rolls 5 and 6, and back rolls 7 and 8, respectwely, all of these rolls being supported and drivenin the usual manner.

According to the present invention the front rolls are weighted by means of aheavy metal roll 10 which bears on the up or front roll 3 and rotates in contact therewith. The opposite ends of this roll have short extenslons or stub shafts 12 projecting therefrom, and two brackets 14, bolted to the front roll brackets 15, have slots 16 therein to receive and guide the shafts 12. Each bracket 14 is ad uStably secured in place by a screw 17 s which passes through a slot formed in a depending flange portion of the bracket and is threaded into the part 15. The weighting roll 10 thus ma be adjusted backward or forward relative y to the drawing roll 3.

As the pressure roll 10 rotates in contact with the drawing roll it collects lint from" the latter roll and this lint is removed. from the pressure roll by means of a clearer shown ject from the opposite ends of the clearer 19, so that whenever the clearer is to be cleaned it can be removed from the machine simply by lifting it out of place, the pins slidmg freely out of their slots.

- It will now be appreciated that this invention provides a very simple and convenient means for weighting and clearing the upper rolls of a spinning frame, roving frame, or like machine. Inasmuch as the clearer is separate from the pressure roll, is very light in weight, and is removable from the machine without disturbin the The brackets 14 have inclined slots i 20 therein to receive two pins '21 which propressure roll, this arran ement avoi s enthat the invention may be embodied in many other forms without departing from the v s irit or scope thereof. It will also be unerstood that other types of clearers than that shown may be used with the roll 10.

Having thus described my invention, what I desire to claim as new is:

1. In a mechanism of the character described, the combination with drawing means including an upper drawing roll, of a weighting roll bearing on said upper draw ing roll, a clearer for one of said rolls, and means for holding said clearer and said weighting roll in their operative positions.

2. In a mechanism of the character described, the combination with drawing means including an upper drawing roll, of a weighting roll bearing on said drawin roll, a clearer for one of said rolls, an means for supporting said weighting roll in different operative relationships to said upper roll.

3. In a mechanism of the character described, the combination with drawing means including upper and lower drawin rolls, of a weighting roll bearing on sai upper drawing roll, a clearer for both said upper and weighting rolls, and means for holding said clearer and said rolls in their operative positions.

4. In a mechanism of the character described, the combination with a spinning frame including upper and lower drawing rolls, of a weighting roll bearing on said upper drawing roll, brackets at the opposite ends of said rolls having slots therein to receive and guide extensions projecting from the ends of said weighting roll, a clearer engaging the surface of said weighting roll, and projections extending from the opposite ends of said clearer and resting in slots formed for them in said brackets.

5. In a mechanism of the character described, the combination with. drawing means including upper and lower drawin rolls, of a weighting roll bearing on sai upper drawing roll, a stationary clearer supported in engagement with said weighting roll, and means for holding said clearer'in its operative position but permitting it to so removed therefrom.
